CARSON CITY, Nev. (AP) -- Invoking national security, President Bush has renewed an exemption allowing the Air Force to keep mum about top-secret operations at a southern Nevada base.
Bush's memorandum said it was of "paramount interest" to exempt the Groom Lake base about 90 miles north of Las Vegas from disclosing classified information.
Also known as Area 51, the mysterious base sits on a dry lake bed and is heavily patrolled. The area is in a no-fly zone.
